The JBO Thread Ring Gauge (GO) — Metric Fine is a precision tool designed to verify external thread diameters with exceptional consistency. Sized to M23 x 0.5 with right-hand threads and a 6g tolerance class, this GO gauge helps machinists, quality inspectors, and manufacturing teams quickly confirm that threaded components meet exact standards. Crafted for durability, it supports demanding work environments and steady inspection workflows.

• High-precision GO gauge for metric fine threads: Quickly confirm that external threads match the M23 x 0.5 (right-hand, metric fine) specification, reducing rework and ensuring consistent fits.
• Hardened steel construction for long service life: Built to resist wear and maintain accurate dimensions even after repeated use in busy workshops.
• Clear, user-friendly design for fast inspections: Simple handling and quick identification of conforming parts, speeding up quality checks and reducing downtime.

This gauge streamlines your quality control by delivering reliable pass/fail feedback in seconds, helping you minimize downtime and keep production on schedule. With its durable build and precise tolerances, you can trust it across multiple shifts, jobs, and teams, ensuring every threaded connection you produce meets your exact specifications.
